The RP03 was the successor to the earlier RP02 multi-platter large disk drive, and the predecessor to the later RP04.
The actual drive was produced by the Information Storage Systems (ISS) division of Sperry Univac , a model 715, and OEM'd by DEC, who added interface electronics.
A maximum of 8 drives were supported per device controller.
